Tom (who can be contacted by e-mail) sends an extract from Jim Rooney's Wikipedia entry:

Jim Rooney is an American music producer whose credits include Nanci Griffith's Other voices, other rooms, Hal Ketchum's Past the point of rescue, Iris DeMent's Infamous angel, John Prine's Aimless love, and many other widely hailed albums.

More detail appeared on the BIB in July 2016, when Jim was nominated for (and later received) an IBMA Distinguished Achievement Award. His autobiography, In it for the long run: a musical odyssey, was published in 2014 by the University of Illinois Press. Read the blog on his website for memoirs of such friends as Bill Keith, Jean Ritchie, and Tex Logan - or if you want to see a photo of Pete Seeger at the age of 2. A video of Jim, with backing band, singing 'Tennessee blues' can be seen here.

Update: Two other dates by the ensemble (16 and 18 Feb.) are shown on the BIB calendar.
